Using an Editmask on a date field, PowerBuilder does not allow a date greater than 12/31/2999. We would like to allow users to enter a ‘high date’ of 12/31/9999 and still use or simulate an editmask or MM/DD/YYYY.
I would suggest using the edit field as a null feature and allowing the user to totally remove the date by selecting and deleting the date. This is much safer than using some big future date. It also has the advantage of working.
